ASTM A500 me ASTM A501e aro nui ana ēnei e rua ki ngā whakaritenga e pā ana ki te hanganga o ngā paipa hanganga maitai waro.
Ahakoa he rite ētahi āhuatanga, he āhuatanga motuhake me ngā whakamahinga anō hoki ō rātou.
Hei muri mai, ka tirohia ngā rerekētanga matua i waenga i te ASTM A500 me te ASTM A501, me te whakamahinga o ēnei i roto i ngā tono rerekē.
Ngā Tukanga Hanga
Ngā Tukanga Hanga ASTM A500
Me hanga ngā paipa ASTM A50 mā roto i ngā tukanga tuimotu, mā roto rānei i ngā tukanga whakarewa.
Me hanga ngā ngongo whakarewa ki te maitai hurihuri-papatahi mā te tukanga whakarewa ātete-hiko (ERW).
Ngā Tukanga Hanga ASTM A501
Me hanga ngā paipa mā tētahi o ēnei tukanga e whai ake nei: te whakarewa hononga kore, te whakarewa pūmau i roto i te oumu (te whakarewa tonu); te whakarewa ātete, te whakarewa pewa rānei i raro i te wai.
Kātahi ka whakamahanatia anō ki te taha whakawhiti katoa, ka whakawerahia mā te whakaiti, mā te hanga rānei, mā ngā tukanga e rua rānei.
Me mahi te hanganga āhua whakamutunga mā te whakamahi i te tukanga hanga wera.
Ngā Tukanga Hanga Rerekē
E whakaaetia ana e ngā paerewa e rua te whakamahi i ngā tikanga hanga paipa tui kore;
Mena ka whakamahia he tukanga whakarewa mō te hanga, ka whakamahia e te ASTM A500 te whakarewa ātete-hiko (ERW), engari ka taea e te ASTM A501 te whakamahi i ngā momo tikanga whakarewa, tae atu ki te whakarewa ātete-hiko (ERW), te whakarewa pewa ruku (SAW), me ētahi atu.
Heoi, e hiahiatia ana e te ASTM A501 kia whakamahanatia te paipa, kia pai ake ai te ōritetanga me ngā āhuatanga ā-pūkaha o te rauemi. Ko te kaupapa o te whakamahana i te paipa he whakapai ake i ngā āhuatanga o te rauemi mā te whakamahana i te paipa i mua i te whakatau i tōna āhua.
Kāore he whakaritenga taipitopito pēnei i te ASTM A500.
Te Whakarōpūtanga o ngā Tohu
Awhe Rahi e tika ana
Ngā Wāhanga Matū
Ina huihuia, he rerekētanga kei roto i ngā hanganga matū o ngā ngongo hanganga maitai waro kua tohua ki ngā paerewa e rua, ASTM A500 me ASTM A501.
I roto i te ASTM A500, he rite tonu ngā whakaritenga hanganga matū o te Wāhanga B me te Wāhanga D, ko te Wāhanga C ia he iti ake te ihirangi waro i te Wāhanga B me te Wāhanga D. I roto i te ASTM A501, he rite tonu te hanganga matū o te Wāhanga A ki te Wāhanga B, ko te Wāhanga C ia he iti ake te ihirangi waro i te Wāhanga B.
I roto i te ASTM A501, he rite te hanganga matū o te Taumata A ki tērā o ngā Taumata B me D o te A500, engari i ngā Taumata B me C ka iti ake te nui o te waro, ka paku piki ake te nui o te manganese, ā, he iti iho te nui o te phosphorus me te whanariki i tērā o te Taumata A.
Ko te nui o te parahi he whakaritenga iti rawa tonu mō ngā reanga katoa.
Ko ngā whakaritenga hanganga matū rerekē e whakaata ana i ngā hiahia motuhake o ngā paerewa e rua mō ngā tukanga whakaputa me ngā tono rerekē, kia mōhio ai kei te tutuki i te rauemi ngā paearu mahi mō te whānuitanga o ngā tono hangarau me te hanganga.
Te Mahi Mīhini
Te Mahi Mīhini ASTM A500
ASTM A501 Mahi Mīhini
Ngā Āhuatanga Mīhini Rerekē
Ko te tikanga he nui ake te kaha o ngā rauemi o te A501 nā te kaha ake o te maitai i te tukanga hanga wera.
Ngā Kaupapa Whakamātautau
Ko ngā whakaritenga rerekē mō ngā tūemi whakamātautau i roto i ngā paerewa e rua e whakaata ana i ngā tukanga hanga me ngā whakamahinga e whakaarohia ana mō ēnei ngongo rerekē e rua.
Ko te paerewa ASTM A500 e hiahia ana ki te Tātari Wera, te Tātari Hua, me ngā Āhuatanga Mīhini, me te Whakamātautau Papatahi, te Whakamātautau Mura, me ngā Whakamātautau Kuru Wedge kia kore ai te tukanga hanga matao e pā kino ki ngā āhuatanga o te rauemi.
E aro nui ana te paerewa ASTM A501 ki te tukanga hanga wera, ā, nā te mea kua tukatukahia ngā hua hanga wera ki te wera i te wā o te tukanga hanga, ka kiia pea he koretake ēnei whakamātautau nā te mea kua whakapūmautia kētia te kirihou me te pakari o te rauemi e te maimoatanga wera.
Ngā Wāhanga Whakamahinga
Ahakoa he mahi hanganga tā rāua e rua, ka rerekē te arotahi.
E whakamahia whānuitia ana ngā ngongo ASTM A500 i roto i ngā hanganga whare, i te hanga mīhini, i ngā anga waka, me ngā taputapu ahuwhenua nā te mea he pai ōna āhuatanga piko matao me te whakarewa.
He pai ake ngā ngongo ASTM A501 mō ngā mahi hanga whare me ngā mahi hanganga e hiahia ana kia kaha ake, kia pakari ake hoki, pērā i te hanganga piriti me ngā hanganga tautoko nui, nā te mea he tino pakari, he pakari hoki.
E whakarato ana ngā paerewa e rua i ngā aratohu mō te hanga ngongo maitai waro kounga teitei, engari ko te kōwhiringa pai rawa atu ka whakawhirinaki ki ngā whakaritenga me ngā here o tētahi kaupapa motuhake.
Mena me pai te mahi a te hanganga i roto i te taiao pāmahana iti, ko te ASTM A501 pea te mea pai ake nā te mea ka nui ake te pakari mai i te hanga wera ka pai ake te ātete ki te pakarukaru. I tetahi atu taha, ki te mea ka hangaia te hanganga mō te taiao o roto, ko te ASTM A500 pea te rawaka, nā te mea ka taea te whakarato i te kaha me te ngāwari ki te mahi e hiahiatia ana, engari he iti ake te utu.
